10/31/2011. Remarks by Bernhard Klein: "This was the proof of concept aircraft of a six/nine-seat pusher turboprop-powered business aircraft, with a crew of one or two pilots. It was the first US aircraft constructed throughout from Dupont 'Kevlar' advanced composite material, hence the 'DUPONT' logo on upper sides of the tail fin. First flown in the USA on September 17, 1984, the type never went into production, and the company went bankrupt in 1998. The aircraft appeared in the 'Airwolf' TV series as the X-400, the plane used by the villain Lou Stappleford in the episode 'Eagles'."
